When Zhin has his Counter stance up, take the time to reload your weapon, switch targets for a moment, or escape if needed , as you'll be hard-pressed to damage him while he's Countering.

While Androxus is channeling Reversal, take the time to reload your weapon, switch targets for a moment, or escape if needed, as it's detrimental to you to attack him during this time.

Remember that Fernando can still Charge while using his Shield. This can enable him to do a little extra damage or reposition himself quickly.

Makoa's Shell Shield will not protect him from your Barrage if you call it down directly on top of him. Watch out for his Dredge Anchor, though, as he can still grab you while you're channeling Barrage.
